I’m 63 and still have a baby tooth. I broke two back molars on popcorn kernels and had to have them pulled a year ago. Was planning to get implants or a bridge this winter, but at the last cleaning the dentist said to not bother. A wisdom tooth has magically appeared and is moving into the space.
Some people even have had 3 sets of teeth..................
[... still have a baby tooth...]
I know a family that has several members that never grew adult teeth. The baby teeth are fine, just are small and never fell out. Dentist told them it was a very rare genetic issue.
